Fraxinus americana, commonly known as White Ash, is a deciduous tree native to North America, characterized by its large size, grey bark, and bright green compound leaves that turn yellow or purple in autumn. It is ideal for large gardens, parks, or as a shade tree in expansive areas, providing a majestic presence and seasonal color changes. Its wood is highly valued for its strength and flexibility.

Care tips
White Ash thrives in full sun, requiring at least 6 hours of direct sunlight daily for optimal growth. It prefers moist but well-drained soils, tolerating a variety of soil types as long as they are not excessively compacted. Watering should be regular during the first few years to establish the tree, especially during dry periods, but once mature, it is quite drought tolerant. A common mistake is planting it in locations where the soil remains waterlogged, which can lead to root rot.
